Abstract (en)
Disclosed is a piezoelectric/electrostrictive element equipped with a piezoelectric/electrostrictive drive unit having a piezoelectric/electrostrictive body, and a film external terminal electrode containing substantially no glass component and being disposed on at least one surface of the piezoelectric/electrostrictive body. The external terminal electrode is an electrode having a laminated structure equipped with a first electrode layer made of a first electrode material being disposed to contact the piezoelectric/electrostrictive body closely and containing a first metal component and a piezoelectric/electrostrictive material, and a second electrode layer made of a second electrode material containing a second metal component and substantially no piezoelectric/electrostrictive material, which the first and second metal components are in the same element system.
